The modulated data may comprise one or more dual tone multi-frequency tones. The gaming headset 524 may receive data, via the chat audio channel, from one or more devices associated with one or more other gamers that are engaged in the play of the particular game. The gaming headset 524 may also be operable to demodulate data, which is received via the chat audio channel, from the one or more devices (e.g., second screen communication devices 506 a, 506 b, . . . , 506 n in FIG. 5A), which may be associated with one or more other gamers that are engaged in the play of the particular game. The transmitted data and the demodulated data may comprise parameter settings, scrambling keys, and/or messages comprising text, images, and/or video content. Some or all of the demodulated data may be converted to audio data, which may be played from speakers on the gaming headset 524.

FIG. 5C shows circuitry of an example headset configured for communicating voice and non-voice data over a chat audio channel. Shown are the connector 210, the radio 220, the microphone 204, the modem 524 c, the DTMF encoder/decoder 524 d, the speakers 216, audio processor 524 a. Also shown are a mixer circuit 550 of the audio processor 524 a and an audio processing circuit 552 of the audio processor 524 a.

The mixer 550 may be operable to combine the voice data signal received via audio input port 558 and non-voice data signal received via input port 560 into a single chat audio band signal. The output of the mixer 550 may be a chat audio band signal such that a receiving device (e.g., game consoles and/or headsets) that does not have a corresponding modem 524 c and/or DTMF encoder/decoder 524 d for demodulating/decoding the non-voice data may be unaware of the presence of the non-voice data and may process the chat audio as is conventionally done for output via speakers to a listener of such device. The listener of such a device may be similarly unaware of the non-voice data with the possible exception that an occasional noise, chirp, or the like may be perceived by a listener of such devices when the non-voice data is modulated onto a carrier that is within the frequency range of human hearing. To further prevent the non-voice data from interfering with the voice data, the mixer 550 may be operable to monitor for periods of silence in the voice data and insert the non-voice data into such periods, may use carriers that are near the extremes of the audible band such that noise, chirps, or the like resulting from the non-voice data are inaudible (or nearly so) to a listener of such a device, and/or may ensure the bursts of non-voice data are sufficiently short so as to not significantly interfere the ability of listeners to comprehend the voice data on the chat audio channel. The output of the mixer 550 may be processed (e.g., voice data may be morphed according to voice morph parameter settings) by circuitry 552 and then output via mic audio out port 554. In another implementation, the signals from ports 558 and 560 may be separately processed by circuit 552 before being combined into a single signal by mixer 550 and then output via port 554.

Chat audio (which may be combined with, or separate from game audio) may be received by the audio processor 524 a via port 556, processed by circuitry 552 (e.g., equalized, undergo chat volume boost, etc.) and then be output via port 562. The modem 524 c may monitor the output of port 562 to detect modulated non-voice data and, upon detection of such data, demodulate the data (e.g., and send it to the CPU 524 f). Similarly, the DTMF decoder 524 d may monitor the output of port 562 for DTMF tones and, upon detecting such a tone, decode it (e.g., and send a corresponding interrupt to CPU 524 f). The speaker(s) 216 may convert the signal out of port 562 to acoustic waves. In some instances, non-voice data in the signal may result in pops, chirps, noise, etc. in the acoustic wave, but through careful control of such data, such pops, chirps, noise, etc. may be kept to a level that does not significantly hinder the experience of the listener using the headset.

FIG. 6 is a flow diagram illustrating exemplary steps for providing inter-headset communications via data over in-game audio, in accordance with various exemplary embodiments of the disclosure. Referring to FIG. 6 , there is shown a flow chart 600 comprising a plurality of exemplary steps, namely, 602 through 614. In step 602, a first gamer listening to a first gaming headset 504 a enters data into a first application running 507 a on a first second screen communication device 506 a. In step 604, the data is communicated from the first second screen communication device 506 a to the first gaming headset 504 a. In step 606, the first gaming headset 504 a receives the data and modulates the received data. In step 608, the first gaming headset 504 a transmits the modulated data on the chat audio channel. In step 610, a second gaming headset 504 b receives the modulated data on the chat audio channel and demodulates the modulated data. In step 612, the second gaming headset 504 b communicates the demodulated data to a second second screen communication device 506 b. In step 614, a second gamer listening to the second gaming headset 504 b consumes the demodulated data utilizing a second application 507 b running on the second screen communication device 506 b.

In accordance with en exemplary embodiment of the disclosure, with reference to FIG. 5A, a gaming headset 504 a may be operable to receive a plurality of audio channels during play of a particular game.

The data that is transmitted and/or demodulated by the gaming headset 504 a may comprise parameter settings, scrambling keys, and/or messages comprising text, image, and/or video content. The gaming headset 504 a, may be operable to convert at least a portion of the demodulated data to audio data, which may be played from speakers on the gaming headset 504 a. The gaming headset 504 a may be operable to receive the data from a second screen communication device 506 a that is communicatively coupled to the gaming headset 504 a. A gamer that is engaged in the particular game may utilize the second screen communication device 506 a to send the data to the gaming headset 504 a.
